IMPROVEMENT IN HOP-DRIERS.

Specification forming part of Letters Patent N9. "90,794, dated May 15,1877; application filed March 12, 1877.

To all whom it may concern:

Be it known that we, SAMUEL R. TEMPLE- TON, JOHN G. TEMPLETON, andJosEPu H. TEMPLETON, of Brownsville, in the county of Linn and State ofOregon, have invented a new and useful Improvement in Apparatus forDrying Hops, of which the following is a specification Figure 1 is avertical longitudinal section of our improved device. Fig. 2 is avertical cross-section of the same taken through the line 90 00, Fig.1,.

Similar letters of reference indicate corresponding parts.

The invention is an improvement in the class of drying apparatus inwhich a furnace and fan-blower are combined, the one to impart heatandthe other to impel heated air through or in contact with thesubstance to be dried.

The invention relates particularly to the construction and arrangementof parts, as hereinafter described and claimed.

A is a cylindrical iron furnace, in the forward part of which is formeda grate, B, and an ash-pit, O. In the forward end of the furnace A isthe door D for putting in the fuel, and an opening, E, to admit air tosupport combustion. 1n the rear end of the furnace A is secured a pipe,F, to conduct the smoke and other gaseous products of combustion to thechimney-flue. The furnaceA is surrounded with a sheet-iron shell, G, ofa greater diameter than said furnace, so as to form an airchamber, H,all around the furnace. I is a fan-blower, which may be driven by ahorse or other convenient power, and the dischargepipe J of which entersthe bottom of the shell G, near its forward end, in an inclineddirectiou.

As the air is forced into the space H it fills said space, becomesthoroughly heated, and escapes through holes 9, in the upper rear partof the shell G, into the drying-room.

The hops to be dried are placed upon a cloth, laid upon racks in layersof any desired thickness, so that the hot air may be forced up throughthem, expelling the moisture and drying the hops very quickly, verythoroughly, and very evenly.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The improved hop-drying apparatus, consistingof the hollow cylinder G, having the apertures g in its upper side, thesmaller concentric furnace A, having grate B, ash-pit O, and door D atone end, and flue F at the other end, a fan-blower, I, andair-conducting tube J, all combined and arranged with the receiver forthe hops, as shown and described.
